Let's divide 805550 by 20
We're looking to find how many times 20 goes into 805550.

Step 1:
20 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 20

On to step 2:
If we divide 80 by 20, we get 4 and a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 80 from 80 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 20

Advancing to step 3:
The number 20 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 40.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 20

On to step 4:
20 can be fit into 55 2 times, resulting in a remainder of 15.
The next digit of our result is 2. 
Result so far: 402.0
Deduct 40 from 55 and we're left with 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 20

Advancing to step 5:
155 divided by 20 is 7 with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 4027.0
Subtracting 140 from 155 leaves us with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 20

Step 6:
If we divide 150 by 20, we get 7 and a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 40277.0
If we take 140 away from 150, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
20 goes into 100 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 40277.5
The remainder is 0 after subtracting 100 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 40277.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 40277.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 40277.5 and a remainder of 0.0.
